[why]
When first time of link training is fail,
eDP would be powered down and
would not be powered up for next retry link training.
It causes that all of retry link linking would be fail.
[how]
We has extracted both power up and down sequence from
enable/disable link output function before DCN32.
We remov eDP power down in dcn32_disable_link_output().

[Why]
There should not be any need to revalidate bandwidth on memory placement
change, since the fb is expected to be pinned to DCN-accessable memory
before scanout. For APU it's DRAM, and DGPU, it's VRAM. However, async
flips + memory type change needs to be rejected.
[How]
Do not set lock_and_validation_needed on mem_type change. Instead,
reject an async_flip request if the crtc's buffer(s) changed mem_type.
This may fix stuttering/corruption experienced with PSR SU and PSR1
panels, if the compositor allocates fbs in both VRAM carveout and GTT
and flips between them.

[Why]
Outside of a modeset/link configuration change, we should not have to
wait for the panel to exit PSR. Depending on the panel and it's state,
it may take multiple frames for it to exit PSR. Therefore, waiting in
all scenarios may cause perceived stuttering, especially in combination
with faster vblank shutdown.
[How]
PSR1 disable is hooked up to the vblank enable event, and vice versa. In
case of vblank enable, do not wait for panel to exit PSR, but still wait
in all other cases.
We also avoid a call to unnecessarily change power_opts on disable -
this ends up sending another command to dmcub fw.
When testing against IGT, some crc tests like kms_plane_alpha_blend and
amd_hotplug were failing due to CRC timeouts. This was found to be
caused by the early return before HW has fully exited PSR1. Fix this by
first making sure we grab a vblank reference, then waiting for panel to
exit PSR1, before programming hw for CRC generation.

[Why]
Observed frame rate get dropped by tool like glxgear. Even though the
output to monitor is 60Hz, the rendered frame rate drops to 30Hz lower.
It's due to code path in some cases will trigger
dm_dp_mst_is_port_support_mode() to read out remote Link status to
assess the available bandwidth for dsc maniplation. Overhead of keep
reading remote DPCD is considerable.
[How]
Store the remote link BW in mst_local_bw and use end-to-end full_pbn
as an indicator to decide whether update the remote link bw or not.
Whenever we need the info to assess the BW, visit the stored one first.

[Why & How]
Currently in dm_dp_mst_is_port_support_mode(), when valdidating mode
under dsc decoding at the last DP link config, we only validate the
case when there is an UFP. However, if the MSTB LCT=1, there is no
UFP.
Under this case, use root_link_bw_in_kbps as the available bw to
compare.

FEAT_SPEv1p2 (optional from Armv8.6) adds a discard mode that allows all
SPE data to be discarded rather than written to memory. Add a format
bit for this mode.
If the mode isn't supported, the format bit isn't published and attempts
to use it will result in -EOPNOTSUPP. Allocating an aux buffer is still
allowed even though it won't be written to so that old tools continue to
work, but updated tools can choose to skip this step.

loop_set_dio is different from the other (__)loop_update_dio callers in
that it doesn't take any implicit conditions into account and wants to

There is no point in doing an fdatasync to write out pages when switching
away from direct I/O, as there won't be any. The writeback is only

While loop_configure simplify assigns the flags passed in by userspace,
loop_set_status only looks at the two changeable flags, and currently
has to do a complicate dance to implement that.
Move assign lo->lo_flags out of loop_set_status_from_info into the
callers and thus drastically simplify the lo_flags handling in
loop_set_status.

CPSW ALE has 75-bit ALE entries stored across three 32-bit words.
The cpsw_ale_get_field() and cpsw_ale_set_field() functions support
ALE field entries spanning up to two words at the most.
The cpsw_ale_get_field() and cpsw_ale_set_field() functions work as
expected when ALE field spanned across word1 and word2, but fails when
ALE field spanned across word2 and word3.
For example, while reading the ALE field spanned across word2 and word3
(i.e. bits 62 to 64), the word3 data shifted to an incorrect position
due to the index becoming zero while flipping.
The same issue occurred when setting an ALE entry.
This issue has not been seen in practice but will be an issue in the future
if the driver supports accessing ALE fields spanning word2 and word3
Fix the methods to handle getting/setting fields spanning up to two words.

scsi_check_passthrough() is always called, but it doesn't check for if a
command completed successfully. As a result, if a command was successful and
the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted
to retry, we will end up retrying the command. This will cause delays during
device discovery because of the command being sent multiple times. For some
USB devices it can also cause the wrong device size to be used.
This patch adds a check for if the command was successful. If it is we
return immediately instead of trying to match a failure.

Atish Patra <atishp@rivosinc.com> says:
Here are two minor improvement/fixes in the PMU event path. The first patch
was part of the series[1]. The 2nd patch was suggested during the series
review.
While the series can only be merged once SBI v3.0 is frozen, these two
patches can be independent of SBI v3.0 and can be merged sooner. Hence, these
two patches are sent as a separate series.

The SBI specification allows only lower 48bits of hpmeventX to be
configured via SBI PMU. Currently, the driver masks of the higher
bits but doesn't return an error. This will lead to an additional
SBI call for config matching which should return for an invalid
event error in most of the cases.
However, if a platform(i.e Rocket and sifive cores) implements a
bitmap of all bits in the event encoding this will lead to an
incorrect event being programmed leading to user confusion.
Report the error to the user if higher bits are set during the
event mapping itself to avoid the confusion and save an additional
SBI call.

If the upper two bits has an invalid valid (0x1), the event mapping
is not reliable as it returns an uninitialized variable.
Return appropriate value for the default case.

Platform firmware event data field is allowed to be 62 bits for
Linux as uppper most two bits are reserved to indicate SBI fw or
platform specific firmware events.
However, the event data field is masked as per the hardware raw
event mask which is not correct.
Fix the platform firmware event data field with proper mask.

Nvidia's Tegra MGBE controllers require the IOMMU "Stream ID" (SID) to be
written to the MGBE_WRAP_AXI_ASID0_CTRL register.
The current driver is hard coded to use MGBE0's SID for all controllers.
This causes softirq time outs and kernel panics when using controllers
other than MGBE0.
Example dmesg errors when an ethernet cable is connected to MGBE1:

This bug has existed since the dwmac-tegra driver was added in Dec 2022
(See Fixes tag below for commit hash).
The Tegra234 SOC has 4 MGBE controllers, however Nvidia's Developer Kit
only uses MGBE0 which is why the bug was not found previously. Connect Tech
has many products that use 2 (or more) MGBE controllers.
The solution is to read the controller's SID from the existing "iommus"
device tree property. The 2nd field of the "iommus" device tree property
is the controller's SID.
Device tree snippet from tegra234.dtsi showing MGBE1's "iommus" property:
smmu_niso0: iommu@12000000 {
compatible = "nvidia,tegra234-smmu", "nvidia,smmu-500";
...
}
/* MGBE1 */
ethernet@6900000 {
compatible = "nvidia,tegra234-mgbe";
...
iommus = <&smmu_niso0 TEGRA234_SID_MGBE_VF1>;
...
}
Nvidia's arm-smmu driver reads the "iommus" property and stores the SID in
the MGBE device's "fwspec" struct. The dwmac-tegra driver can access the
SID using the tegra_dev_iommu_get_stream_id() helper function found in
linux/iommu.h.
Calling tegra_dev_iommu_get_stream_id() should not fail unless the "iommus"
property is removed from the device tree or the IOMMU is disabled.
While the Tegra234 SOC technically supports bypassing the IOMMU, it is not
supported by the current firmware, has not been tested and not recommended.
More detailed discussion with Thierry Reding from Nvidia linked below.

We found a timeout problem with the pldm command on our system. The
reason is that the MCTP-I3C driver has a race condition when receiving
multiple-packet messages in multi-thread, resulting in a wrong packet
order problem.
We identified this problem by adding a debug message to the
mctp_i3c_read function.
According to the MCTP spec, a multiple-packet message must be composed
in sequence, and if there is a wrong sequence, the whole message will be
discarded and wait for the next SOM.
For example, SOM → Pkt Seq #2 → Pkt Seq #1 → Pkt Seq #3 → EOM.
Therefore, we try to solve this problem by adding a mutex to the
mctp_i3c_read function. Before the modification, when a command
requesting a multiple-packet message response is sent consecutively, an
error usually occurs within 100 loops. After the mutex, it can go
through 40000 loops without any error, and it seems to run well.

i2c-atr catches the BUS_NOTIFY_DEL_DEVICE event on the bus and removes
the translation by calling i2c_atr_detach_client().
However, BUS_NOTIFY_DEL_DEVICE happens when the device is about to be
removed from this bus, i.e. before removal, and thus before calling
.remove() on the driver. If the driver happens to do any i2c
transactions in its remove(), they will fail.
Fix this by catching BUS_NOTIFY_REMOVED_DEVICE instead, thus removing
the translation only after the device is actually removed.

If GuC fails to load, the driver wedges, but in the process it tries to
do stuff that may not be initialized yet. This moves the
xe_gt_tlb_invalidation_init() to be done earlier: as its own doc says,
it's a software-only initialization and should had been named with the
_early() suffix.
Move it to be called by xe_gt_init_early(), so the locks and seqno are
initialized, avoiding a NULL ptr deref when wedging:

This can be easily triggered by poking the GuC binary to force a
signature failure. There will still be an extra message,
xe 0000:03:00.0: [drm] *ERROR* GT0: GuC mmio request 0x4100: no reply 0x4100
but that's better than a NULL ptr deref.

for_each_possible_cpu
The 'np' device_node is initialized via of_cpu_device_node_get(), which
requires explicit calls to of_node_put() when it is no longer required
to avoid leaking the resource.
Instead of adding the missing calls to of_node_put() in all execution
paths, use the cleanup attribute for 'np' by means of the __free()
macro, which automatically calls of_node_put() when the variable goes
out of scope. Given that 'np' is only used within the
for_each_possible_cpu(), reduce its scope to release the nood after
every iteration of the loop.

Currently, HIP08 devices does not register the ptp devices, so the
hdev->ptp is NULL. But the tx process would still try to set hardware time
stamp info with SKBTX_HW_TSTAMP flag and cause a kernel crash.
